[0043] Combine the following Figures 1 to 14 The translation-rotation structure 10 provided in this embodiment is described in detail.
[0044] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the utility model provides a structure 10 that translates and rotates at the same time, including a frame 100, a mounting base 200, a material tray 300, a rotating seat 320 and a guide shaft 400. The mounting base 200 is slidably arranged on the frame 100 along a preset direction; the material tray 300 is used to place battery cells, and the material tray 300 is rotatably arranged on the mounting base 200; the rotating seat 320 is rotatably arranged on the mounting base 200, and the rotating seat 320 is fixed to the material tray 300; one end of the guide shaft 400 is swingably arranged on the frame 100, and the other end of the guide shaft 400 is connected to the rotating seat 320. The guide shaft 400 is used to extend and retract relative to the rotating seat 320 during the swinging process, and drives the mounting base 200 to translate along a preset direction, and at the same time drives the material tray 300 to rotate relative to the mounting base 200.
[0045] “The other end of the guide shaft 400 is connected to the rotating seat 320, and the guide shaft 400 is used to extend and retract relative to the rotating seat 320 during the swinging process” includes two implementations. In one implementation, the guide shaft 400 does not have the telescopic function, the guide shaft 400 is slidably connected to the rotating seat 320, and the guide shaft 400 is used to slide and cooperate with the rotating seat 320 during the swinging process. The rotating seat 320 slides along the guide shaft 400, and the guide shaft 400 moves telescopically with the rotating seat 320 as a reference. In another implementation, the guide shaft 400 has the telescopic function, one end of the guide shaft 400 is connected to the rotating seat 320, and during the swinging process of the guide shaft 400, the rotating seat 320 pulls the guide shaft 400 to extend and retract during the translation process.
[0046] In the first embodiment, the rotating seat 320 is provided with a guide hole 321; the structure that translates and rotates at the same time also includes a linear bearing 410, which is fixed to the guide hole 321, and the end of the guide shaft 400 away from the swing connection with the frame 100 is movably arranged in the linear bearing 410 and the guide hole 321.
[0047] Reference Fig. 9 and Fig.10In this embodiment, the rotating seat 320 is provided with a guide hole 321; the rotating seat 320 is provided with a guide hole 321, and the end of the guide shaft 400 away from the swing connection with the frame 100 passes through the rotating seat 320 through the guide hole 321; the structure 10 for translating and rotating while also including a linear bearing 410 connected to the rotating seat 320, the linear bearing 410 is sleeved on the guide shaft 400 and limited to move with the guide shaft 400, and is subject to the movement restriction of the mounting base 200 and the swing restriction of the guide shaft 400. The length of the guide shaft 400 passing through the rotating seat 320 will change with the moving position of the mounting base 200 relative to the frame 100. The rotating seat 320 is limited by the restriction of the guide shaft 400 and the movement of the mounting base 200. During the movement of the mounting base 200, the rotating seat 320 will rotate synchronously, and since the rotating seat 320 is fixed to the material tray 300, the material tray 300 is driven to rotate synchronously, thereby realizing the translation and rotation of the material tray 300.
[0048] One end of the guide shaft 400 is fixed. During the swinging of the guide shaft 400, the mounting base 200, the rotation and the rotating seat 320 can only translate in a preset direction. The distance of one end connected to the swinging of the guide shaft 400 will increase or decrease. Therefore, the rotating seat 320 slides along the axial direction of the guide shaft 400 and swings with the guide shaft 400, ensuring that the translation of the mounting base 200 and the rotation of the material tray 300 are realized synchronously.
[0049] Reference Figure 4 and Figure 5 In the motion diagram, a is the linear bearing 410, b is the material tray 300, c is the guide wheel 210, d is the guide rail 110, e is the guide shaft 400, and f is the fixed-axis rotating component 500. The rotation and translation of the material tray 300 can be achieved during the rotation of the guide shaft 400.
[0050] One end of the guide shaft 400 that is swingably connected to the frame 100 is fixed, and the guide shaft 400 swings around the end of the swingable connection in the horizontal plane. The other end of the guide shaft 400 moves in an arc-shaped trajectory. During the swinging of the guide shaft 400, the mounting base 200 can only translate in a preset direction, and the rotating seat 320 slides axially along the guide shaft 400. The rotating seat 320 can only rotate synchronously with the guide shaft 400, and synchronously drives the material tray 300 to rotate. The material tray 300 is translated by the translation of the mounting base 200, and the material tray 300 is driven to rotate at the same time, so as to achieve translation and rotation at the same time, with a simple structure, fast rhythm, and improved feeding efficiency.
[0051] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8In this embodiment, the structure 10 for translating and rotating at the same time further includes a guide rail 110 and a guide wheel 210; the guide rail 110 is fixed on the frame 100 along a preset direction, the guide wheel 210 is connected to the mounting base 200, and the guide wheel 210 cooperates with the roller of the guide rail 110 along the preset direction.
[0052] The guide wheel 210 rolls with the guide rail 110, and the guide wheel 210 can only roll along the guide rail 110. The mounting base plate 200 can only move along the direction of the guide rail 110, limiting the installation base plate 200 from translating along a preset direction. During the swinging of the guide shaft 400, the installation base plate 200 also always translates along the preset direction without offset.
[0053] Reference Fig. 9 and Fig.10 In this embodiment, the structure 10 that translates and rotates at the same time also includes a slewing bearing 330 and a slewing transition plate 340; the outer ring of the slewing bearing 330 is fixed on the mounting base 200, the material tray 300 and the slewing transition plate 340 are respectively fixed on the opposite sides of the inner ring of the slewing bearing 330, and the rotating seat 320 is fixed to the slewing transition plate 340.
[0054] The swing of the guide shaft 400 drives the rotating seat 320 to rotate relative to the mounting base plate 200, and synchronously drives the material tray 300 to rotate relative to the mounting base plate 200. The material tray 300, the inner ring of the slewing bearing 330, the rotating transition plate 340 and the rotating seat 320 are connected in sequence from top to bottom, the rotating seat 320 is fixed to the inner ring of the slewing bearing 330 through the rotating transition plate 340, and the material tray 300 is fixed to the top of the inner ring of the slewing bearing 330.
[0055] Reference Fig.10 , Fig.11 and Fig.12 In this embodiment, the translation and rotation structure 10 further includes a fixed axis fixing seat 510, a bearing 520 and a fixed axis 530; the fixed axis fixing seat 510 is fixed on the frame 100, and the fixed axis 530 is rotatably connected to the fixed axis fixing seat 510 through the bearing 520; the fixed axis 530 is provided with a fixing hole 531, and one end of the guide axis 400 away from the rotating seat 320 is fixed in the fixing hole 531. One end of the guide axis 400 is fixed to the fixed axis 530, and the guide axis 400 swings through the bearing 520. The fixed axis fixing seat 510 is used to keep one end of the guide axis 400 in a fixed position, and the bearing 520 is used to realize the swing connection of one end of the guide axis 400.
[0056] Reference Fig.13 and Fig.14In this embodiment, the structure 10 for translating and rotating at the same time further includes a limit assembly 600, which is fixed on the material tray 300; the limit assembly 600 is used to cooperate with the mounting base 200 during the swinging of the guide shaft 400, so that when the mounting base 200 translates to the first position, the length direction of the material tray 300 is parallel to the length direction of the mounting base 200; or when the mounting base 200 translates to the second position, the length direction of the material tray 300 is perpendicular to the length direction of the mounting base 200, and the moving stroke of the mounting base 200 between the first position and the second position along the preset direction is the effective moving stroke of the mounting base 200 along the preset direction.
[0057] During the translation of the mounting base plate 200, the guide shaft 400 and the material tray 300 rotate synchronously, and the rotation position of the material tray 300 relative to the mounting base plate 200 and the translation stroke of the mounting base plate 200 are limited by the cooperation of the limit assembly 600 and the mounting base plate 200. The mounting base plate 200 translates between the first position and the second position, and the material tray 300 rotates within the angle range of parallel and vertical relative to the mounting base plate 200. In other embodiments, the translation stroke of the mounting base plate 200 and the rotation stroke of the material tray 300 can be set according to actual needs.
[0058] Reference Fig.13 and Fig.14 In this embodiment, the limit assembly 600 includes a first limit member 610 and a second limit member 620; the first limit member 610 and the second limit member 620 are fixed at two opposite corners of the material tray 300 in the length direction and the width direction; the first limit member 610 and the second limit member 620 are used to abut against the edges of the long sides on both sides opposite to the mounting base 200 when the mounting base 200 is translated to the first position, so as to prevent the material tray 300 from continuing to rotate relative to the mounting base 200.
[0059] Specifically, the first limit member 610 and the second limit member 620 are used to abut against the long edges on both sides opposite to the mounting base plate 200 when the material tray 300 rotates relative to the mounting base plate 200 to the point where the length direction of the material tray 300 is parallel to the length direction of the mounting base plate 200, so as to prevent the material tray 300 from continuing to rotate relative to the mounting base plate 200.
[0060] The mounting base 200 moves to the first position, and the material tray 300 rotates relative to the mounting base 200 until the length direction of the material tray 300 is parallel to the length direction of the mounting base 200. At this time, the first stopper 610 and the second stopper 620 respectively abut against the two side edges of the mounting base 200, and the mounting base 200 is located between the first stopper 610 and the second stopper 620, preventing the material tray 300 from continuing to rotate relative to the mounting base 200, and the translation also stops. It should be noted that: "continue to rotate" means to continue to rotate in the same direction, but in the opposite direction, that is, the guide shaft 400 swings in the opposite direction, driving the mounting base 200 to translate in the opposite direction, and the material tray 300 can rotate in the opposite direction.
[0061] Reference Fig.13 and Fig.14 In this embodiment, the first supporting portion 650 and the second supporting portion 660 are respectively provided on the two side edges opposite to each other at the position of the mounting base 200; the limiting component 600 also includes a third limiting member 630 and a fourth limiting member 640; the third limiting member 630 is arranged side by side with the first limiting member 610, and the fourth limiting member 640 is arranged side by side with the second limiting member 620; the third limiting member 630 is used to abut against the first supporting portion 650 when the mounting base 200 is translated to the second position, and at the same time, the fourth limiting member 640 abuts against the second supporting portion 660 to prevent the material tray 300 from continuing to rotate relative to the mounting base 200.
[0062] Specifically, the third limit member 630 and the fourth limit member 640 are used to respectively abut against the first abutting portion 650 and the second abutting portion 660 when the material tray 300 rotates relative to the mounting base 200 to the point where the length direction of the material tray 300 is perpendicular to the length direction of the mounting base 200, so as to prevent the material tray 300 from continuing to rotate relative to the mounting base 200.
[0063] During the rotation of the material tray 300 relative to the mounting base 200, the mounting base 200 rotates relative to the material tray 300 between the first stopper 610 and the second stopper 620, and between the third stopper 630 and the fourth stopper 640. When the mounting base 200 is parallel to the material tray 300, the opposite side edges of the mounting base 200 abut against the first stopper 610 and the second stopper 620 respectively, and when the mounting base 200 is perpendicular to the material tray 300, the first abutting portion 650 and the second abutting portion 660 abut against the third stopper 630 and the fourth stopper 640 respectively, so as to achieve the travel limit of the translation of the mounting base 200 and the rotation of the material tray 300.
[0064] Specifically, when the material tray 300 is parallel to the mounting base plate 200, the first stopper 610 and the second stopper 620 are respectively abutted against the mounting base plate 200 for position limiting, and the third stopper 630 and the fourth stopper 640 are not abutted against other parts. When the material tray 300 is rotated to be perpendicular to the mounting base plate 200, the first abutting portion 650 and the second abutting portion 660 on both sides of the mounting base plate 200 are respectively abutted against the third stopper 630 and the fourth stopper 640 for position limiting, and at this time, the first stopper 610 and the second stopper 620 are not abutted against other parts.
[0065] Reference Fig.13 and Fig.14 In this embodiment, the first limiting member 610 has a first limiting head 611 for abutting against the mounting base plate 200; the second limiting member 620 has a second limiting head 621 for abutting against the mounting base plate 200; the third limiting member 630 has a third limiting head 631 for abutting against the first abutting portion 650, and the fourth limiting member 640 has a fourth limiting head 641 for abutting against the second abutting portion 660; the first limiting head 611, the second limiting head 621, the third limiting head 631 and the fourth limiting head 641 are all elastic round head structures; the third limiting head 631 and the first limiting head 611 are spaced apart along the length direction and width direction of the material tray 300, and the fourth limiting head 641 and the second limiting head 621 are spaced apart along the length direction and width direction of the material tray 300. The elastic round head structure can buffer the abutting force between the limiting component 600 and the mounting base plate 200 , thereby reducing the loss and damage between the material tray 300 and the mounting base plate 200 .
[0066] Reference Figures 1 to 14According to a structure 10 for translating and rotating at the same time provided in this embodiment, the working principle of the structure 10 for translating and rotating at the same time is as follows: the structure 10 for translating and rotating at the same time is applied to the material tray 300 in the automation equipment, and the material tray 300 needs to be translated and rotated. Two actions that traditionally need to be performed separately are completed synchronously through a set of driving structures, so as to achieve translating and rotating at the same time. The structure 10 for translating and rotating at the same time includes a material tray 300, a limit assembly 600, a slewing bearing 330, a rotating transition plate 340, a mounting base plate 200, a guide wheel 210, a rotating seat 320, a linear bearing 410, a guide shaft 400, and a fixed axis rotating assembly 500. The fixed-axis rotating assembly 500 includes a fixed axis 530, a bearing 520, a bearing sleeve 540, an elastic retaining ring 550 for the shaft, a rotating fixed seat 560, and a fixed-axis fixed seat 510. The fixed axis 530 is covered with two deep groove ball bearings 520 and a shaft sleeve, and is limited by an elastic retaining ring 550 for the shaft. Finally, the fixed axis 530 is fixed to the fixed-axis fixed seat 510 through the rotating fixed seat 560. The fixed axis 530 can realize fixed position rotation without jumping up and down. The guide axis 400 passes through the fixing hole 531 on the fixed axis 530 and is locked to realize the function of the guide axis 400 rotating around a fixed point.
[0067] The fixed axis rotating assembly 500 and the guide shaft 400 form a rotating pair. The fixed axis fixing seat 510 is fixed in the frame 100. The guide shaft 400 passes through the linear bearing 410 to form a moving pair. The linear bearing 410 is connected to the rotating seat 320 through screws. The rotating seat 320 is connected with a slewing bearing 330 to form a rotating pair. The mounting base 200 is connected to the guide wheel 210 and then placed in the guide rail 110 to form a moving pair. Figure 4 and Figure 5In the figure, a is a linear bearing 410, b is a tray 300, c is a guide wheel 210, d is a guide rail 110, e is a guide shaft 400, and f is a fixed axis rotating assembly 500. During the rotation of the guide shaft 400, the tray 300 can be rotated and translated. A pair of limit assemblies 600 with an angle of 90° are installed on the tray 300, which can limit the rotation angle of the tray 300 to 90°. During the rotation of the tray 300, the angle between the guide shaft 400 and the tray 300 remains unchanged. The rotation angle of the guide shaft 400 is consistent with the rotation angle of the tray 300, so the rotation angle of the tray 300 can be well controlled by setting the rotation angle of the guide shaft 400. Through calculation, the degree of freedom of the structure is, and only one prime mover is needed for the entire mechanism to obtain a certain motion trajectory. And it is applicable to a wide range of scenarios. The translation stroke can be adjusted by adjusting the distance between the fixed-axis rotating assembly 500 and the guide rail 110, and the installation position of the fixed-axis rotating assembly 500 can be adjusted by changing the angle between the material tray 300 and the guide shaft 400. In addition, multiple groups of translation and rotation structures 10 can be vertically arranged on a frame, and each translation and rotation structure 10 can be independently controlled or synchronously controlled to complete batch operation.
[0068] The translation-rotation structure 10 provided in this embodiment has at least the following advantages:
[0069] The swing of the guide shaft 400 drives the mounting base 200 and the material tray 300 to translate synchronously, and at the same time drives the material tray 300 to rotate relative to the mounting base 200, thereby achieving translation and rotation at the same time, with a simple structure, fast rhythm, and improved feeding efficiency.
[0070] The embodiment of the utility model also provides a battery cell feeding device. The battery cell feeding device includes a frame and a plurality of structures 10 that rotate while translating; the plurality of structures 10 that rotate while translating are arranged side by side vertically on the frame, and the plurality of structures 10 that rotate while translating are controlled independently or synchronously. The problem of independent translation and rotation drive, complex structure and low efficiency of the battery cell feeding equipment can be improved. The plurality of structures 10 that rotate while translating can also be arranged side by side horizontally and spaced apart, and driven and controlled independently or together.
[0071] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
